Jason Aldean has apologized to his wife and fans for apparently inappropriate behavior at a Los Angeles club.

The married country music star was snapped by the paparazzi appearing to embrace American Idol's Brittany Kerr at a Sunset Strip bar in recent days.

Aldean has now penned an open letter to express regret for his actions and call for privacy for his family.

"The truth is that I screwed up. I had too much to drink, let the party get out of hand and acted inappropriately at a bar," the singer wrote.

Aldean continued: "I left alone, caught the bus to our next show and that's the end of the story. I ultimately ended up embarrassing my family and myself. I'm not perfect, and I'm sorry for disappointing you guys.

"I really appreciate being able to work through this privately with my family and for all your continued support."

Aldean married high school girlfriend Jessica Ussery in 2001. The couple have two daughters.

His fifth studio album Night Train is released later this month in the US.
